Abstract: Coastal sand dune ecosystems are facing threats and pressures across Europe, but the quantification of the exact impacts is not easy, particularly when natural and anthropic effects are overlapping. In order to tackle this question, during two years sand movement has been measured in pilot dune plots located in the Northern Spanish coast. We aimed at correlating the waves height, wind velocity and tidal range with the temporal changes measured in the beach-dune systems. The role of littoral processes on the sand movement is quantified by fitting different regression models using R, in order to discuss the influence of marine variables, climate change and human activities in the changes identified in coastal sand systems, which also affects Spanish coasts.
